As best illustrated in FIG. 6, the coupling between the cavity 214 and the protrusion 244 allows for movement to plus and minus seventeen degrees from the centerline. In other embodiments, the coupling may allow for more movement. In yet other embodiments, the coupling may allow for less movement.

The locking portion 222 of the first member 210 is configured to engage or interact with the locking portion 252 of the second member 240. For example, the locking portions 222 and 252 may engage or contact each other when the members 210 and 240 are disposed in a specific configuration to help retain the members 210 and 240 in that configuration. In the illustrated embodiment, the locking portions 222 and 252 are configured to help retain the members 210 and 240 in their straight or linear configuration.

In the illustrated embodiment, the locking portion 222 of the first member 210 is a groove or opening 224. The groove or opening 224 is located or disposed within the cavity 214. Specifically, the groove or opening 224 is defined by the sidewall 216 that forms or defines the cavity 214. In the illustrated embodiment, the groove or opening 224 extends around the cavity or opening 214 to form a complete circle. In other embodiments, the groove or opening 224 has a different size or shape.

In the illustrated embodiment, the locking portion 252 of the second member 240 is a ridge or projection 254. The ridge or projection 254 is located on the protrusion portion 244 of the second member 240. Specifically, the ridge or projection extends about the surface of the protrusion portion 244 to form a complete circle. In other embodiments, the ridge or projection has a different shape or size.

The groove or opening 224 is configured to receive the ridge or projection 254 to lock or help retain the members 210 and 240 in a specific configuration or orientation with respect to each other. In the illustrated embodiment, the groove or opening 224 is configured to receive the ridge or projection 254 when the members 210 and 240 are placed in their straight or linear configuration to lock or help retain the members 210 and 240 in such a configuration. In other embodiments, the locking portions may have different configurations to lock the members in place with respect to each other.

FIG. 8 is a cross-sectional view of first member 210. As discussed above, the first member 210 includes a coupling portion 212 (cavity or opening). The first member 210 also includes a second coupling portion 272 (protrusion or protrusion portion). Accordingly, the implant 200 includes many members that may be serially coupled together to form the bodily implant 200 such as a penile implant. More or less of the members may be serially coupled together to form different sized implants. For example, in one embodiment, 15 members may be coupled together to form an implant of a first length or size and in another embodiment, 20 members may be coupled together to form an implant of a larger size.

In the illustrated embodiment, the implant 200 includes a rear end assembly 280 and a front end assembly 290. The rear end assembly 280 includes a rear end member 282 and a rear end cap 284.

Specifically, the lumen 262 is configured to house the members. In other words, the members, including the first member 210 and the second member 240, are disposed within the lumen 262 of the sheath 260. In the illustrated embodiment, the sheath 260 is coupled to and extends from the rear end cap 284 to the front end cap 294. In some embodiments, the sheath 260 may be formed of a bioabsorbable material.

As illustrated in FIG. 11, the implant may be placed or disposed within a penis P of a patient or user. In the illustrated embodiment, a first implant 200A and a second implant 200B are disposed or placed within the penis of the patient. The implants are placed in a parallel or side-by-side relationship (with the urethra of the patient extending between the implants). In some embodiments, only one implant is disposed within the patient. Additionally, in some embodiments, the implant is placed or disposed in another portion of the body of the patient.

In use, a user or patient may straighten their penis to place the implant 200 in its first, straight, or linear configuration. For example, a user may grasp and lift an end of their penis to straighten their penis and place the implant 200 in its first, straight, or linear configuration. The lifting and end portion or straightening of the implant 200 will cause locking members of the members to engage with the locking members of the adjacent members. In this configuration, the implant 200 is retained in its first, straight, or linear configuration.

A user or patient may push their penis down or into a non-linear position. This movement will overcome the locking force of the locking portions and will release the implant 200 from its first, straight, or linear configuration. Specifically, the implant 200 will be returned to its second, curved or non-linear configuration.
